Mission Overview

To test the effectiveness of aluminum and carbon fiber on reducing radiation levels

Radiation levels double at 12,000m above ground

Hypothesis: Both materials will lower radiation exposure to nonlethal levels, but aluminum will be block more radiation

Mission Overview Continued

This mission is being conducted to show what materials should be used in aircraft to maintain a safe environment for humans

Carbon fiber and aluminum are commonly used on aircrafts
